Taunton, count'yof Bristol, state-of-Massachusetts, have invented an Improvementv in Clutch Mechanism for lteverselirea'ring, of whic'hthe following is a specification. This invention relatesto clutch -.mechanisms, and has for its object to construct 'a very powerful. friction clutch-mechanism 10. wl 1ich is simple in construction and easily operated. It may be applied to reverse gearing connectin a-driving-shaft with adriven shaft, such or instance, as .shown'. in my -application for Lettersv Patent #390,566, filed August29,-l9 07, wherein two rotatable me'mbers are employed, one having-means for connecting it with a driving-shaft'and the other having meansfor connectingi't' with a driven-shaft; or it may-apply, to a one-way transmission .means having two rotatable members, one of which is connected with the driving-shaft and the other with thedriven-shaft. 1 p

The invention comprises improvements in the rotatable'members, whereby they serve as cooperative parts of the clutch-mecham. ism, also improvements in'the clutch-plate and, also improvements in y the operating ;1neans. I v g Figure 1 i a side elevation of ,a clutch mechanism embodying this invention, it being represented as applied to the 'form of reverse gearing shown in my said -ap lication. Fig. 2 is =1 longitudinal vertica sec- Figs. 3 and 4 are details to be referred to. 1 Fig. '5 is a longitudinal verticalsectionof the clutch-mechanism embodying this invention applied to a simple form of transmission means Referring to Figs. 1 to 4 inclusive, th reverse gearing to which the-clutch-mechanism is herein shown as applied, for the sake of illustration, comprises a driving-shaft 12,

Several r lo stb spur ear'af thereon", ranged about said: spur gear andinengagement therewith, a plate supporting the bearings for said pi'nions, an internal gear d having a hub d which is mounted" upon and secured .to thedriven shaft-e by .aset-screw (F, a cylindrical which receivesYsaid internal gear havingl at oneendaalclutchengaging, wall f, and having seeured to its" opposite end the aforesaidplate bf, soithat the gears are-,i-nclosed within "said case. f.

of the rotatablemembers of the clutch-inechanism a'nd'thei'internal gear d the other rd tatable member, and said members are con.-

-nected, one with the driving-shaftand the other-withtthe driven-shaft; The opposite to sides of thec lutch-engaging wall f of. the member f are both iofmed with-flat engaging-faces and are of large area. The head or crownof the internal gear (1 is formed exteriorly with a flat engaglng-face, adapted to engage one of the engaging-faces of the wall f. The fperi heral wall of the internal.

gear is made to t the interior ofthe case to thereby provide a long bearing-for said ear. w 'Referring to Fig. 5, a case f'having'the clutch-engaging wall f, is shown, but said case is connected with the driving-shaft. a, by a set-screw a) instead of by meansof gearing, and in lieu ofthe internal gear d having a flat engagingdaceat the end, a disk d is provided, which is secured to the drivenshaft e-by a set-screw (P, and one side of said disk is formed with a flat en aging-v face to engage oneof the engagingaces of the clutch-engaging wall fof the member f. ,Said disk is shown as having a hub d within the case which is 'mounted-on the driven-shaft e t-oprovide a long. bearing for it, and one end of said hub enters, a bushing d, arran ed;in a recess formed in the interiorof t e member f. ,Thus in both forms shown it will be observed that, one of the rotable' -members is connectedwith I the wall provided with two oppositely disposed .enga 'ng-faces, and that the other rotatable ,mem er is arranged adjacent the aforesaid member and is provided with an engagingface to engage one of the engaging-faces of the'cioresaid member. The two rotatable members are movableiwith respect to each ,other, .such movement being permitted by a sliglll endwise movement of the shafts, or one only of said members may be movable with respect tothe other. As engagement oflsaid parts is frictional buta very slight movement of either or both is required.

The hub d of the member d extends througlra center hole in the end wall f of member f, and has a screw-threadedportion d at-or near itsl'outer end which receives upon it an adjustable abutment or collar for ing fingers to be described, I

A circular clutch-plate or .disk It? is mounted on the hub d, adjacent the end-- fwjall f," and is held. against rotationinde" pendentiy of the hub cZ',' and is -permittec'l to.

These pin's'are fixed to the. member f, and theactuating-plate is -.n1ovable on said pins when moving I the clutch-plate into and out of engagement with theendwa'll'f, The actuating-plate i's'thussupported and its fmovement' guided. j The movementofthe clutch-plate is but'slight as its engagement is frictional. Thus it will be seen that the clutch-plate is slidably conposed so that but a. slight movement of 'the" Qnected with oneof; the. rotatable members and thatfthe actuating-plate is slidablyicon- -nected with the other'rota'table member,'andthat the -.t wo plates are .contiguouslydisactuating-plate is required to ,move' the clutch-plate into: engagement with the clutchengaging wall f";

For the purpose'of moving the clutch plate 9', an adjustable abutment is'employed which consists of a cellar it, a plate h? and an anti-friction ring it. v The collar h is mounted on the screw-threaded portion of the hub cl Fig. 2,}o'r the hub d Fig. 5, andis adjustable thereon... The plate 70?, see

and contiguous said collar, and is slidably shown as having. its center, hole provided with keyways which receive keys h projecting radially from the hub.v This plate is madeyo'flbrass or some difierent metal from the collarfand ring. It'is 'revented 'fromrotating independently of t e .hub, 1 and is employed as a meansfor preventing 'inde-' pendent rotation of the collar h, and to accomplish this result-one ormore screws 72,"

which receive the toes i of the clutch-operlatingfingers if. Saidfingers a're'pivoted at i to ears i providedlion the actuating-plate 9.

They extend in'thegeneral direction of the driven-shaftfeg and engage, at their outer "ends, a cone 7' which is mounted loosely upon the" shaft 6. The cone. 1' is arranged to slide along on the shaft 6 for the purpose of moving the fingers i and it has a collar mount ed on it'provided with trunnions j projected outwardly which are eng'aged by the bars of the actuating-lever. "As the actuating-lever is moved onitspivotal connection with the bar m, said sliding cone is moveddn one or the other direction on the shaft 6, and when moved: in one direction" the fingers willbe separated, causing the toes z to bear'hard against the anti-friction ring, and the latter being held against rearward movement ,causes' the pivot-supports ofsaid fingers, to bodily move and thereby movethe actuatingplatea-nd clutch-plate toward the end wall f',- and as the clutch-plate engages said end wall the member fi-will, or may be moved slightly toward the'memberjck ,Also as the toes thus bear hard against the abutment on the member d,said member is'm'oved slightly tow-ard'the member f,'engaging the innenenmember. f is thus engaged exteriorly by the clutch plate and interiorly by the member cl. "It Wlll be observed'that the member is engaged by the clutch-plate and by the member (Z atapproximately the same time andgaging face of the, end wall f thereof. The

thatengagement is effected by the same When thesliding cone is moved in the opposite d rection, the fingers are permitted to resume their normalpositions and pressure driven-shaft ej-is. adapted to be rotated-l in the same direction as the driving-shaft, and to thus rotate it the case 7 and the'intermtl' earv dare revolved in the same direction gaid driven'rshaft is also adapted to remainat I rest while the driving-shaft continues to ro and to thus'holdit at "rest the internal geaf is heldat rest and the is 'ievol'ved'lf Said driven-shafb is also adapted to be 1 0- tated infa direction opposite to the dire'c'tion of rotation of the driving-shaft; and to thus mtateit th case isheldatrest andthe internal gear revolved in a direction opposite sha. a,

As the actuating-plate connected with the case only and the fingers are pivotally connected with said actuating-plate it will ton t e direag ap rotationlofthe drivingbe seen that 'said fingers will not be carried gers about the shaft them, toswing outward by centrifugal acrotarily about the shaft except when the case revolves, hence when the case is at rest and the gear revolves said fingers will remain'at'rest. 'Rotary movement of the finas a tendency to cause tion, consequently, it is a decided advantage not, to have them rotate whenthe gear only 1s revolved and thedriven-shaft e is thereby driven-in a direction opposite to the direc-- tion of rotation of the driving-shaft. -By
